WATER-HEATING DEVICE.

SPECIFICATION forming part of Letters Patent No. 476,949, dated June 14,1892.

" Application filed May 25, 1891. Serial No. 394,026. (No model.)

To all whom, it may concern:

Be it known that I, 'lIMoTnY ROGERS, a citizen of the United States,residing at Springfield, in the county of Clark and State of Ohio, haveinvented certain new and useful Improvements in WVater-I-IeatingDevices, of which the following is a specification, reference being hadtherein to the accompanying drawings.

My invention relates to certain new and useful improvements inwater-heating devices, the peculiarities of which will be hereinafterfully described and claimed.

In the accompanying drawings, forming a part of this specification, andon which like reference-letters indicate corresponding parts, Figure 1represents a plan view of a portion of a stove-top with my devicemounted thereon, the grate being broken away in part; Fig. 2, a verticalsectional View on the line 2' .2 of

Fig. 1; Fig. 3, a detached View of a plurality of loops of pipeconstituting the water-heating chamber; Fig. 4, a transverse sectionalView on the line no 00 of Fig. 3, showing the position of the loops withregard to the burner; and Fig. 5, a side View of a portion of Fig. 3,showing the inlet and discharge ends of the pipe.

The letter A designates a stove-top of a gas oline or other suitablevariety of stove having an opening B therein,in which is mounted aburner O. The grate D rests on said stovetop and is preferably providedwith radiating webs E, connected together and preferably having a heightsufficient to support a'cooking utensil out of contact with the pipeconnection between the Water-heating chamber and the water-tank F. Thewater-heating chamber shown in Figs. 1 and 2 consists of a single loopG, surrounding said burner and adapted to be supported within theopening B by means of its connection with the said tank F. After formingthe loop or bight of pipe about the burner a bend in each end of theloopcarries the pipe above the stove-top, whereby the said loop Or maybereadily inserted within the stove-opening by removing the grate andsetting the tank in position. One end of the pipe is turned up, as shownin Fig. 2, and provided with a series of holes and a cap or plug H,having a disk-like top, as shown in Figs. et and 5, whereby the waterdischarging from said pipe will be deflected sidewise and prevented fromspurting upward-within the tank. The other end I of'the pipe isYsimplyinserted within the tank and, being lower than the perforated end, isadapted to form the inlet-pipe to the water-heating chamber, where thetemperature of the water is raised as it circulates about the lightedburner, and it is then discharged from the perforated end.

The grateD is notched orotherwise adapted to fit about the pipes as theybend upward from the water-heating chamber.

Referring to Fig. 3, a plurality of loops G G are shown as constitutingthe waterheating chamber. This form has special advantages in that itpresents a large amount of heatingsurfaee within a small space. Theinlet end I of the pipe is in this case connected to the bottom of thewater-tank, as shown in Fig. 5, by any suitable form of joint, such asby a collar J, adapted to form the coupling with said tank. The pipe,starting from the inlet end, curves around the burner, making a bend atK and, returning in a reverse direction, forms a loop at L opposite andadjacent to the one at K. Then the return-bend carries the pipe aroundand above the former loop until it is adjacent to the bend at K anddirectly above the same, and whence it is carried above the stove-topand into the tank, as indicated by Fig. 5. It will be observed that boththe above forms of loop-namely, the single and the plurality formhave aspace between the pipe connections, Where they emerge from thestove-opening B. This allows the flexible pipe-chamber to be sprung openin order to pass the burner branch or support, which might otherwiseinterfere with placing the water-heating chamber in position. Thesectional view in Fig. 4 shows the action of the flames upon thesurrounding loops of pipe and illustrates the advantage of a pluralityof loops in intercepting the flames. It will be observed that the loopsare so formed as to present a gradual ascent for the circulating waterin its passage back and forth around the lighted burner and back againto the water-tank. If desired, the entrance-pipe I may also have anupward bend above the stove top, as indicated by the dotted lines inFig. 5. This form of heating-chamber, composed of a plurality of loopsarranged about a burner, has been found to possess special advantages inheating water. The amount of heating-surface presented by these loopsfacilitates the heating of water, and the peculiar form promotes thecirculation away from The force of the returning ing device, as abovedescribed and illustrated.

The construction of the water-heating chamber out of one or more loopsof pipe reduces the weight of the chamber over other forms 1 ofconstruction, so as to allow it to be easily: supported by means of itsconnection with the water-tank, which is the preferred con struction.There is, also, no looseningof joints caused by the expansion andcontraction of the supporting connections, since in this device thewater-heating chamber is preferably entirely detached from either stovegrate ori top.

Referring to Fig. 3, it will be seen that the colder water from saidtank enters the heat-i ing-chamber at its lower portion, and circu- Ilating back and forth within the reversed loops it finally returns tothe water-tank, thelast portion of its travel within the water heatingchamber being through the inner loop constituting the hottest portion ofthe chamber.

This construction carries out the wellknown law governing the bestresultsin heating -liquidsnamely, that the water or liquid 1 shouldenter the heating-chamber at its colder portion, and as the temperatureof the water rises it should be subjected to the highest degree of heat.In other words, the hottest water should be circulated through thehottest Referring to the drawpart of the chamber.

ings, Fig. 3, it will be seen that this result is secured by locatingthe loop delivering into 1 the tank within the inside of the other loopsand in closest proximity to the flames of the burner.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. The combination, with a stove-top anda water-tank supported thereon,of a grate ex tending over the hole in said top to support a cookingutensil and notched to the hole at one side of said grate, and awater-heating chamber consisting of a looped pipe, both ends beingconnected to said tank and adapted to extend along above the stove-topto the said hole, then bent downward through said notched grate andoutward horizontally in reverse direct-ions under the same, leaving aspace between the opposing bends, whereby the watenheating chamber andtank may be readily set on or removed from said stove-top, the gratebeing adjusted above said looped pipe by means of said notched portionfor the admission of the pipe below the grate.

2. The combination, with a water-tank, of a water-heating chamberconsisting of a plurality of loops of pipe communicating with said tankand adapted to embrace a burner, said loops being laid in reversedirections with a space between the opposing return-bends.

3. The combination, with a water-tank, of a water-heating chamberconsisting of a plurality of loops of pipe communicating with said tank,the said loops being laid in re versely-horizontal directions, but withascending inclination as the loops extend back and forth, the opposingloops being separated by a space at their return-bends.

4. As an improved article of manufacture, a water-heating chamberconsisting of a plurality of loops of pipe laid in reverse directions,with a space between the opposing bonds of said loops.

5. As an improved article of manufacture, a water-heating chamberconsisting ofa plurality of loops of pipe laid in reversely-horizontaldirections, but with ascending inclination to facilitate the passage ofthe water from said pipe as it rises under the influence of
